Duality defects, anomalies and RG flows

Christian Copetti
(Oxford)
Abstract

We review the construction of non-invertible duality defects in various dimensions. We explain how they can be preserved along RG flows and how their realization on gapped phases contains their 't Hooft anomalies. We finally give a presentation of the anomalies from the Symmetry TFT. Time permitting I will discuss some possible future applications.

The rank varieties and complexities of modules

Jialin Wang
(Nanyang Technological University)
Abstract
Fix a finite group G and an algebraically closed field F of characteristic p. For an FG-module M, the complexity of M is the rate of growth of a minimal projective resolution of M. The rank varieties introduced by Carlson are used as a tool to determine complexities in a more computational way. In this talk, I will introduce some basic properties of rank varieties and complexities and then review some known results on complexities of modules for symmetric groups.
